Sprecher+Schuh CA7-43-00-120 Contactors
Product Overview
Sprecher+Schuh CA7-43-00-120 is an industrial-grade AC contactor, belonging to the CA7 series, designed for medium and high current control applications. The contactor adopts a modular structure and is suitable for motor control, power distribution and industrial automation systems, providing reliable switching and protection functions.
Core Features
High-performance electrical specifications
Rated current: 120A (AC-3 load, 400V)
Control voltage: standard coil voltage optional (such as 24V DC, 230V AC, etc., the specific model needs to be confirmed)
Mechanical life: ≥1,000,000 operations
Electrical life: ≥100,000 times (under rated load)
Rugged and durable structure
Silver alloy contacts, arc resistance, wear resistance, suitable for frequent switching occasions.
The arc extinguishing system is optimized to reduce contact erosion and improve long-term reliability.
Modular accessory support (such as auxiliary contacts, mechanical interlocks, delay modules, etc.).
Safety and compatibility
Complies with IEC 60947-4-1 and UL/CSA standards (specific certification depends on the model).
Suitable for a variety of applications such as three-phase AC motors, resistive loads, transformers, etc.
Easy to install and maintain
Screw terminals or spring terminals (depending on the model) support large-section wire connection.
Can be installed on DIN rail (35mm standard rail), saving space.
Typical applications
Motor control (pumps, fans, compressors, etc.)
Industrial power distribution systems (automatic switching, capacitor compensation cabinets)
Heavy machinery (cranes, conveyor belts, crushers)
Renewable energy (photovoltaic inverters, wind power control systems)
